摘要
我国北方大型岩溶泉域有近百个,其汇水面积多在数百至数千平方公里。泉域内岩溶地下水系统结构复杂、运动途径迂回曲折。搞清其结构特征及地下水运动途径是建立水文地质概念模型和资源评价数学模型的基础。本文以三姑泉为例,探讨了利用地质结构场、水化学场、同位素场、水动力场相结合的方法,获得多重信息,相互补充,相互印证,建立较为逼真的岩溶地下水系统概念模型和数学模型,并在此基础上,对整个系统及各个子系统进行了水资源评价。
There are nearly a hundred large karst springs in North China. The total drainage area of the spring systems makes several hundred to several thousand square kilometers. Within the spring areas, the karstified geologic structures, through the circuitous paths of which groundwater flows, are quite complex. To make clear the structural features of karstified formations will provide the base for establishing hydrogeologic conceptual model,and also mathematical model for groundwater resources evaluation.In the paper the Sangu spring system is taken as an example to approach the methods in combination of geologic structure, hydrocbemistry, environmental isotopes and hydrodynamics.In this way, manifold information may be acquired, intersupplemented and interverified, so that a more realistic conceptual model and mathematical model of a karst groundwater system may be established.
